SPECIFICATION forming part of Letters Patent No. 251,944, dated January 3, 1882. i

' Application filed December 11, 1880. (ModeL) To all whom c't may concern Be it known that I, EDMUND W. QUINCY, a

citizen of the United States, residing at Decawill enable others skilled in the art to which it:

appertains to make and use the same, reference I being bad to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specificatioinin which- 7 Figure 1 isa top plan of the forward frame of a corn-planter with my improvement, Fig. 2 is a-sectional elevation in the line was in Fig. l. Fig. 3 is an elevation, partly in section, of the seed measuringand dischargingdevices. Fig. 4 is a perspective of the seed-cup disk.

This invention relates to check-row cornplanters, or corn-planters designed to plant in cross-rows, or rows transverse to the path of the machine, of that class in which the seeding devices are operated by a knotted wire or rope stretched across the field. The invention consists in constructions and combinations hereinafter described, and set forth in the claims hereto annexed.

0 3 corn-planter (designated byletters A) and seedboxes and runners, (designated respectively by the letters B O.) D is a'bar placed transversely on the planter, 3 5 and extending beyond the seed-boxes B.

E is a rock-shaft journaled in bearings e to the bar D, and has a forked lever, 6 on each of its ends. A head or cross-bar, F, is fixed to each end of. the bar D, which beads are pro- 0 vided at their ends with guide-pulleys f and guards f, for the'knotted check-row chain G.

H is a spiral spring connected at one end with an arm, 6, on the shaft E, and at its other end with one of the heads 1*.

The foregoing parts, described by referencelett-ers, are parts of an ordinary check row corn-planter of the class shown, and may be constructed in any usual manner.

The drawings show the forward frame of a j A standard, I, connects the seed-box B with the runner O. J is the seed-cup wheel or disk, consisting FOf a cylinder with a series of radial chambers or seed-cups, j, in its periphery, and a corresponding number of ratchet-teeth, K, also in {its periphery, but at one end of said cylinder,

as shown at Fig. 4. The seed-cup wheehJ is journaled on a bolt, 1, in a recess, L, in the standard I, with the cups j beneath. the seedbox and the ratchet-teethK exterior to the standard. A flange, M, projects from the pe- 6o ripheral wall of the recess L, and surrounds theprojecting end of the wheel J, and has an opening, m, in its upper side, through which a pawl, N, may pass to engage with the ratchetteeth K. Theupperendot' thepawlNishinged to an arm, n, on the shaft E. A cap, P, covers the outer end of the wheel J, and is held in place by ears q with keys q, and by a nut, q, on the bolt 1, which bolt passes through the cap-plate 1?. By removing the nut qand keys 70,

g, the cap P may be removed for access to the seed-wheel J to clean it, or to substitute other wheels with seed-cups of different capacities, or for any other purposes.

The recess L has an opening, R, in the lower side of its peripheral wall, which opening communicates with the open rear end of the runner G. The recess L has also anopening, S, in the upper side of its peripheral wall, which communicates with the interior of the seed-box. T is a cut-ofi' pivoted or hinged at t, and held by a spring, t, which permits it to yield upward in the usual manner.

In operation the planter is drawn along the knotted check-row chain, and the knots gact successively on the forked levers e to oscillate them backward in the usual manner. Oscillating the levers a and the rock-shaft E backward will force the pawls N. against the ratchetteeth on the seed-wheels J and give a partial o rotation to each seed-wheel, which partial rotation willbring one of the seed-cups over the discharge-opening R and allow it to discharge its contained seed. The knot g, escaping from the forked lever e, will release the rock-shaft and permit the spring H to restore the rockshaft and pawls N to their normal positions and ready for the action of the next knot 9, thus giving an impulse or partial rotation to the seed-wheels at each backward partial rotation of the rock-shaft, and thereby imparting an intermittent rotary motion in one direction to said seed-wheels, and discharging a measured quantity of seed at each movement of said seed-wheels.

It is not deemed necessary to describe the action of the cut-oft nor the manner in which the seed-cups are filled, as both operations are usual in planters hafing similar seed-wheels.

The lower part of the seed-wheels are close above the runners 0, and the seed isdischarged from the seed-wheels into and through the open rear ends of the runners, and being discharged thus close to the ground will prevent scattering the seed by the forward motion of the planter, and thereby dispense with the com mon lower discharge-valve.

Seed -cup wheels rotating in horizontal planes, and having axial seed-cups or cups parallel with the axis of the wheel, may be used instead of the seed-cup wheels herein described, and the pawl be readily and easilyarranged to impart to such horizontal wheels an intermittent rotary motion in one direction.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a corn-planter, in combinationtwiih a seed-cup wheel having a ratchetwheel formed in one of its ends and periphery, and with a knotted check-row chain or wire, a rockshaft witha pawl adapted to impart an intermittent rotary motion in one direction to the seed-cup wheel, substantially as and for the purpose specified.

2. In combination with the standard I, 0011- meeting the seed box and runner, and with the seed-wheel locatedinthe standard I, the cap P,

vboxes and seed-wheels having radial peripheralseed-cu ps and peripheralratchet-teeth, the rock-shaft having a pawl at each end for imparting movement to the seed-wheels, and

forked levers for receiving movement from a knotted check-row chain or wire, substantially ,as and for the purpose specified.

In te sti mony whereof I affix mysignature .inpresence of two witnesses.
